8x - 13 = 5x + 17
8x -5x = 17 + 13
3x = 30
x = 30/3
x =10
DE = 8x - 13 = 8(10) - 13 = 80 -13 = 67
EF = 5x + 17 = 5(10) + 17 = 50+ 17 = 67
DF = x + 21 = 10 + 21 = 31
# 5
6x - 77 = 3x + 4
6x - 3x = 4 + 77
3x =81
x=81/3
x = 27
WX = 6x - 77 = 6(27) - 77 = 85
XY = 3x + 4 = 3(27) + 4 = 85
WY = 5x-31 = 5(27) -31 = 104
